Bug(?) in Fastreport Designer
small demo: create a new project, drop some FastReport components on it, add functions and variables in code using frxReport.AddFunction() and frxReport.Variables.AddVariable(), then call Designer. In the variables pane you see your variables, in the functions pane you see your functions.
Now load a fr3 file. Suddenly all your variables disappear, but your functions don't.
This bug haunts me from FR4 onward. Of course I can use "OnGetValue()", which I do forced by this "feature".
The Forums probably aren't the right place to "report bugs".
Have you raised a Support Ticket?
You may have noticed that I wrote "Bug(?)". As this has been the case for a long time, and many others will have noticed, I think this isn't a bug but works as designed. I'm looking for someone stating "this is by design. Set property "foo" to "bar" to avoid deleting all your variables" or something like this. Maybe I have to alter the FastReport sources.
